Letters Patent No. 100,548, dated March 8, 1870;

@uneven/:ENT IN PREPARIN'G BUTTON-HOLE rvvrs'nY The Schedulereferred .to in theinaLelbers 'atent and making of the sanne To all whom @t mag/'concern Be it known that I, ROBERT Monmsou, ot' Yonkers, in the-county of Westchester, and State of New York, have invented a certain -new and useful Improvement in the Manufacture ofvBu'tton-Hole Twist; and that the following is a full and correct description thereof, reference being had to the accompanying drawings forming a part of this specification and to the letters of reference thereon. v l My invention relates to the preparation of buttonhole twist for spooling or winding in balls or* other forms, in` which it is put up. to render it marketable.

In the manufacturero oi' button-hole twist, it has been the practice to gather the threads from a nurnfber of bobbins of finished twist, say eightA or twelve, and wind them'together, without twisting upon` a reel, spool, or bohbin, tobe afterwardwound uponspools or in balls in the same condition, that is, with eight `or twelve 'threads or strands wound together without twisting. This is done for the convenience of tailors- .or trimmers, who, knowing the number of strands so wound together lupon the spool or ball, can measure at once the requisite length of button-hole twist for a coat, or number of coats, sothat in4 giving out a great numberof coats, as in the wholesale clothing manufacture,- time is saved, .besides the economy of getting at the exact quantity of sc expensive amarticle of silk; but the twist so prepared for u sev will separate or tangle when cut o' from the spool, and therefore it has been the placticeto tie it in a knot or wrap it in its length in paper, both of which. modes areobjectionable.

Braiding the twist has been resorted to, but this isalso objectionable, as the operation of braiding'hy machinery raises a beard or.' nap which'requires to be singed. i

4The object of my invention is to retain-the advantages of the winding of a number of threads or strands together without twisting, and also to keepthe strands together, so as'to dispense with knottiug or wrapping 'at length in paper, and yet be convenient for use of trimmers and working tailors.

My invention consists in` bindingthe vthreads of twist together by one or more threads of very tine silk coiled lightly around them, or 4by eoiliiig one of the threads of twist around the others, preparatory to winding it on spools orballs' for the market, substantially as hereinafter described.

Figure l of the drawings represents a side elevation of the mechanism forkbinding `the twist.

Figure 2, a plan View, with the reel removed.

Figure 3, view of the bound' twist, with one binder coiled `around it. t

Figure 4, view of the twist, with two binders coiled around it.V

`Letter a represents the vbound strands of twist bound by a single binding-thread, infig. 3, or by two binding-.threads b b', iig. 4, the binding-thread o r threads being coiled lightly around the straight-laid threads or strands of button-hole twist.

' I prefer touse a binding-thread ot' different ,color from the twist, but do not limit my invention thereto, as I canaccomplish some of the objects of my invention by the use of'one of the threads of' twist as a binding-thread for the others.

'The mode of binding that I prefer is touse two binding-threads ofvery'iine silk, augenzine or tz-ain,

v the latter preferred, coiled in opposite directions around the twist.

The extremelightness and softness of this binding-- tlirea'd causes it to cling to the twist it encircles, and it practically holdsthe twist vwithout knottiug or4 braidin". v j Llhe coils of the binding-threads should not be closer together than as'shown in the drawings, and may be further apart, so that they are close enough to practically operate to hold the twist together when a length encircle the twistl with their gossamer grasp, the object not being to resist a force 'pulling the threads' of twist apart, but merely to lightly hold the threadstogether when cut o from the spool, the tram I' prefer to use for a binder being about sixteen miles to the ounce.

Letters c d represent two spools containing augen-4 -zine77 or tram, mounted respectively in `bracket-beau ings c1 d1, supported by hollow vertical spindles', one of which passes through the other so as to leave a h ollow axis through which the twist a passes from the supply-spool cto a reel or spool, f, which turns on a spindle, f', and has a grooved cone-pulley by whichit is driven by a round bami, g, from a smaller grooved cone-pulley, 71.

` The binding-spools c and d have grooved pulleys c2 'and di attached to their respective spindles, their`driving-belt i, driven by the pulleyj, being looped around both'pulleys c2 and cl2, and aA loose guide-pulley j', so

as to rotate the spools in opposite'directions.

The supply-spool has a light tension-spring, e', resting on the twist wound upon it to keep the twist straight while being bound. v

Instead of the supply-spool e, on which the twist is wound eight or twelve strands together, the requisite nuniber of' singly-'wound supply-spools may be used and their threads gathered together, so as to pass up through the axis of the binding-spools, and

instead ofthe winding-reel f, the usual mechanism for spool or ball-winding may be used. l

Each of the binding-spools c and d has a curved thread-guide c3 and da, the curve of the thread-guide being a segment of a circle, the center of which is .the axis of the binding-spool, the binding-thread passing over it is preventedfroni 'dragging sidewise upon Y its spool.
